I had the same issue a few weeks back, solved by reinstall of MCS app.
It broke when I updated Moitessier HAT and crashed a lot of i2c stuff...
Thomas;
Would you expect the Seatalk1 input to work better with a PullUp connected to it?
I'm not sure what's on the MCS board so would it make a difference you beleive?
Also since you completed the magic with ST1 input, are you considering making an output as well?
